Examples of org.apache.lucene.codecs.DocValuesProducer$SortedSetDocsWithField

org.apache.lucene.codecs.DocValuesProducer
A simple implementation of {@link DocValuesProducer#getDocsWithField} that returns {@code true} if a document has any ordinals.
Codecs can choose to use this (or implement it more efficiently another way), but in most cases a Bits is unnecessary anyway: users can check this as they go.

    // TODO: can we avoid iterating over fieldinfos several times and creating maps of all this stuff if dv updates do not exist?
    
    for (Entry<Long,List<FieldInfo>> e : genInfos.entrySet()) {
      Long gen = e.getKey();
      List<FieldInfo> infos = e.getValue();
      DocValuesProducer dvp = segDocValues.getDocValuesProducer(gen, si, IOContext.READ, dir, dvFormat, infos, getTermInfosIndexDivisor());
      dvGens.add(gen);
      for (FieldInfo fi : infos) {
        dvProducersByField.put(fi.name, dvp);
        dvProducers.add(dvp);
      }
